SPECIFICATION forming -part of Letters Patent No. 376,531, dated January 17, 1888.

v Application filed March 17, 1887. Serial No. 281,258. (No model.)

.To all whom it may concern.-

Beit known that I, A UGUsT LENTZ, a subject of the King of Prussia, residing at Stettin, in the Kingdom of Prussia,German Empire, have invented a new and useful Device for Charging Retcrts, of which the following is aspecication. r

This invention relates to an apparatus for charging retort-furnaces having any number 1o of retorts and adapted for the treatment of coal and other materials.

The invention consists in the various fea'- tures of improvement hereinafter more fully pointed out.

The accompanying drawing represents a sectional side elevation of my improved apparatus.-

The letter A represents a tube curved in the shape of a segment of a circle. The upper zo end of this tube is provided with a funnel, t, through which the charge is inserted. The lower end of the tube opens into the month of the retort R to be charged. The height of the tube A is proportioned to the length of the retorts about as four to three. The tubes may be closed, as shown, or they maybe open on one side similar to a trough.

The charge is delivered into the mouth of the funnel t either by means of a shovel or by 3o means of a box or containerprovided with a slide to regulate the charging of the retorts. When the charge is delivered into the tube, it is shot along the door of the retort by reason of the considerable height of fall. Subsequent vlots encounteron their way the heaps of previously-charged material., push them farther, and remain in front of them, and so ou until the retort is gradually charged to the mouth. The height of the tube must also be proportionate to the nature of the material to be charged; but the speed of the descent'of the materials can also be indueneed by more or less violently projecting the materials into the funnel; hence it becomes possible to charge horizontal retorts of any desired lengthheavily or lightly at will.

In retort-furnaces forgasmaking with several rows of retorts the charging apparatus may be combined with a traveling platform or with a fixed charging-floor, as represented. 5o In this case the material to be charged is placed on the floor F, and the lube A embraced by tlie eyed end of a shaft or carriage, b, provided with wheels d, to move the tube A from one retort to another. For each horizontal row of retorts one tube is usually required; but the apparatus can be arranged so that one tube suhices to charge a whole set of retorts. In this case the tube is raised or lowered by a suitable lifting mechanism. This mechanism 6o is shown to consist of a chain, a, suspended from the carriage or shaft b, the other end of which is connected to the lower end` of tube A. By revolving the shaft b the chain a will be wound upon it, and thus the tube will be raised. With shifting platforms the tube can be attached to the platform so that it travels with the same in front of the retorts. In this manner apparatuses of various sizes and containing any number of retorts can be charged either from ixed or from traveling platforms.

What I claim isriDhe feeding mechanism for retorts, consisting of the curved feeding-tube provided with a feed-hopper, the Wheeled shaft for carrying said tube, and a chain, as described, for raising and lowering said tube, substantially as specitied.

In testimony whereof I have signed my name to this specification in the presence of two snb- 8o scribing witnesses.
